Prodigy is an excellent sound card; both it and the M-audio revolution 7.1 and 5.1 use the same chip, there ENVY24-HT. Which ever one u get you can\'t go wrong.
Personally I have owned the revo 7.1 for over 1 year and its sound quality is clean, and accurate. The last creative card I ever purchased was 5 years ago. I refuse to buy CL because they are always behind the curve in terms of sound quality and innovative features. However Creative has bought out and destroyed the mainstream gaming soundcard market. They are a monopoly and eventually I will probably get one 2 years from now as a gaming card. There is no more competition left, CL\'s last competitor sensura which both the revo and prodigy use for the gaming dsp was purchased by CL 7 months ago for 6 million. So that means no more support for the sensura builds.
Audigy 2 is still crap, it resamples Redbook or mp3 to 48khz, plus to much noise interference in there sound card pcb layout design, and bloated half ass drivers.
Just to further illustrate creative labs monopoly, there audigy 4 still resamples, uses the same dsp EAX, other then new external features it the same card recycled.
The only thing left to save the gaming Sound Card industry is custom made sound engines for games, like carmack did for doom 3.
